GAS-BURNER FOR COOKING STOVES OR RANGES.

SPECIFICATION forming part of Letters Patent No. 456,139, dated July 21,1891.

' Application filed September 8, 1890. Serial No. 364,807. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS F. DOWNEY, a citizen of the United States,residing at Detroit, county of Wayne, State of Michigan, have invented acertain new and useful Improvement in Gas-Burners for Cooking Stoves orRanges; and I declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification.

In the drawings, Figure 1 is a plan view illustrating my burner inposition in a stove. Fig. 2 is a front view of the same with partsbroken away to illustrate the mechanism. Fig. 3 is a longitudinalsection from front to rear ofthe stove.

Cooking stoves and ranges vary so greatly in the size of their fire-potsand the relative arrangement of the grate with respect to the stove-lidsand the relative arrangement of the water-back, if one is employed, withrespect to the other parts that a large variety of burners have had tobe made to accommodate these different conditions, and even then theburners have not been adapted properly for the different conditions metwith in use.

It is the purpose of my invention to produce a burner the parts of whichshall be adj ustable, so that it may be fitted to any of the va- -riousvarieties of stoves and ranges. To this end the supporting-frame is madeadjustable lengthwise to reach and rest upon the ordinarygrate-supports, and the burners for the stove-openings are madeadjustable bot-h laterally and vertically to bring them centrallybeneath the openings and into any desired proximity therewith, and Iprovide a burner for the water-back or water-front, as the case may be,which is made adjustable up and down to conform to the position of thewaterback or water-front and adjustable in a direction from front torear of the stove to accommodate any particular projection of the saidwater-back or Water-front, and I provide also a similarly-adjustableburner for heating the ovens, the purpose being that when once adjustedto conform to the requirements of the stove or range these parts may berig- D is the supporting-frame of my burner. It is provided withadjustable sliding sections 0', adapted to be set out lengthwise of theframe or drawn in, as may be necessary, to

fit the frame to any particular grate-rest. c

A idly set in place and connected up in the represents slots in theframe and said adjustable sections.

0 is an upright section of the frame, pro- Vlded Wll/h a similaradjustable slide 0 and slots o.

D represents burners for the respective stove holes or openings in thetop of the stove. The stem of each burner is sleeved through a holder D,and is made adjustable up and down therein through the medium of asetsorew d or equivalent. This holder D has a shank passing through theslot c,'and back of the frame 0 is provided with a nut 01.

It is thus apparent that this burner maybe adjusted up and down and solocated at any desired position below the stove-hole, and when properlyadjusted may by the set-screw d be fixed in this adjustment. Again, theholder D may be adjusted in adirection from side to side of the stove inthe slot 0 and so given its exact lateral position with respect to thestove-hole, and be then firmly fixed in this adjustment by tighteningthe nut cl.

E .is the burner for heating the water-front or water-back, as the casemay be. The stem of this burner is sleeved through the support E in thesame manner as last described, and may be adjusted in any position up ordown through the medium of the'set-screw e. The shank of this supportpasses backward through the slot 0, and nuts 6 e are placed both on thefront and rear of the supporting frame, so that the said burner may beadj usted in a direction from front to rear of the stove, and in thisway the burner may be given. any desired position with respect to thewater-front and be made to'conform to the different conditions Whichexist in different stoves or ranges.

F is a burner adapted for the ovens. Its arrangement is similar to thatof the burner E, it being provided with a support F, setscreW f, andfront and rear adjusting-nuts f5 f By these means this burner may belikewise adjusted to any particular altitude with respect to the oven,and may be adjusted to give it any desired position in front of theoven.

It is apparent that this burner is adapted at once for all the varyingconditions met with in the usual classes of stoves and ranges, and avery considerable expense is thus saved in the fitting up of the saidstoves and ranges for the use of gas.

I would also have it understood that While the burners here shown aredesigned more particularly for natural gas the contrivanee is equallyWell adapted for the burners used with gasoline, vapor, or the vaporfrom crude petroleum or kerosene, and I would have it understood that myclaims contemplate such employment of it as Well as with natural gas.

Each burner is provided at its lower end with a gas-jet g and With anair-mixer g of any usual construction, and when the burners are once setthey are connected by pipes G, which lead thereto from a manifold-valvechamber H, and this chamber is provided with independent valves II foradmitting gas independently to one or more of said burners, so thateither burner may be cut 05 entirely if it is not necessary to use thesame.

I do not here lay special claim to the manifold-valve chamber and itsvalve, per 56, because I purpose to make the said manifoldvalveapparatus the subject of a separate application for Letters Patent.

WVhat I claim is- 1. The combination, with gas-burners for cookingstoves or ranges, of an extensible frame carrying the burners andadapted to rest upon supports Within the stove or range, and means foradjusting the burners to different positions on the extensible frame,substantially as described.

2. The combination, with gas-burners for cooking stoves or ranges, of anadjustable frame carrying the burners and adapted to rest on supportsWithin the stove or range, and means for adjusting the burnersvertically and laterally'on the frame, substantially as described.

3. The combination of a frame adapted to rest on supports Within acooking stove or range having a Water-front, pot-hole burners carried bythe frame, a burner for the Waterfront, and means for adjusting theburners vertically and laterally on the frame, substantially asdescribed.

a. The combination, With gas burners for a cooking stove or range, ofthe adjustable frame D comprising extensible sections C and slots 0 c,the gas-burner supports D E F, and means for vertically adjusting theburners in the supports, substantially as described.

In testimony whereofI sign this specification in the presence of twowitnesses.
